Study 7 Integrated Respiratory Care Practice with 12 free online flashcards. Review key terms, definitions, and concepts with this interactive flashcard deck.
Which measures assess oxygenation, and which reflect ventilation?
Oxygenation is assessed with PaO₂ and SpO₂; ventilation is reflected in PaCO₂ and pH. Supplemental oxygen may improve hypoxemia but does not, by itself, correct inadequate ventilation.
What pH ranges indicate acidemia and alkalemia?
Acidemia is a pH below 7.35; alkalemia is a pH above 7.45.
In COPD, what does low pH, high PaCO₂, and elevated HCO₃⁻ suggest?
A low pH with elevated PaCO₂ indicates respiratory acidosis. Elevated HCO₃⁻ suggests prior or chronic renal compensation; acidemia may indicate acute worsening on top of chronic CO₂ retention.
Which findings make a COPD exacerbation urgent?
Drowsiness, significant work of breathing, tachypnea, and hypoxemia are urgent warning signs. Escalate promptly; do not delay action to obtain another ABG.
What changes can make NIV unsafe or inadequate?
Worsening consciousness, inability to protect the airway, hemodynamic instability, or failure to improve can make NIV unsafe or inadequate and require urgent reassessment for invasive airway support.
What SpO₂ target is often used for COPD or CO₂ retention?
For many adults with COPD or CO₂ retention, an SpO₂ target of 88–92% is often used. Individualize the target to the clinical situation and orders.
What do elevated pH, low PaCO₂, and PaO₂ of 52mm Hg on FiO₂ 0.60 indicate?
Elevated pH with low PaCO₂ indicates respiratory alkalosis. A PaO₂ of 52mm Hg despite an FiO₂ of 0.60 indicates severe oxygenation impairment.
Does a low PaCO₂ rule out respiratory failure?
No. A low PaCO₂ does not rule out respiratory failure. Severe hypoxemia, high oxygen needs, rapid breathing, and fatigue can signal impending failure.
What tidal-volume range is recommended for adults with ARDS?
For adults with ARDS, the cited guideline recommends tidal volumes of 4–8mL/kg predicted body weight.
What plateau-pressure target is recommended for adults with ARDS?
For adults with ARDS, monitor for a plateau pressure below 30cm H₂O.
What is the first priority when a ventilated patient suddenly triggers an alarm?
Assess the patient immediately: check oxygenation, chest movement, airway and tube position, breath sounds, and hemodynamics while urgently calling for assistance.
What can cause a high-pressure ventilator alarm?
Causes include secretions or a kinked or obstructed tube, biting, bronchospasm, coughing, or reduced lung compliance.
